When: Thursdays-Sundays, 6 p.m. Continues through Oct. 19
If you don't live in an air-conditioned place, the Missouri Botanical Garden (4434 Shaw Boulevard; www.mobot.org) is one of the coolest places to be when the summer sun goes down, thanks to its multitudes of flora. Fortunately, the garden will be open late once again on select nights during Garden Party Lights, a massive installation of multimedia light projections designed by AVI Systems and Theatrical Concepts. Doors open at 6 p.m. Thursday through Sunday (July 6 to October 19), with the light show starting once it's dark. There will be food and beverage sales at both the covered Biergarten and the Cohen Cantina. Tickets are $10 to $20, and Thursdays and Sundays are family nights, with $3 tickets for kids younger than twelve.
